%description
Variable selection methods have been extensively developed for analyzing
highdimensional omics data within both the frequentist and Bayesian
frameworks. This package provides implementations of the spike-and-slab
quantile (group) LASSO which have been developed along the line of
Bayesian hierarchical models but deeply rooted in frequentist
regularization methods by utilizing Expectation–Maximization (EM)
algorithm. The spike-and-slab quantile LASSO can handle data irregularity
in terms of skewness and outliers in response variables, compared to its
non-robust alternative, the spike-and-slab LASSO, which has also been
implemented in the package. In addition, procedures for fitting the
spike-and-slab quantile group LASSO and its non-robust counterpart have
been implemented in the form of quantile/least-square varying coefficient
mixed effect models for high-dimensional longitudinal data. The core
module of this package is developed in 'C++'.
